the plate size is 9x3" or for younger people 229x75mm
mine is only a 5 letter plate so not a bad fit as for the boys in blue its early days yet.

How did you mount it in there? I have the same bumper (genuine one) and it comes with a bracket. But it sticks out a bit too far for my liking, that looks quite neat.
are you talking about the air duct that go's behind the grill if so i just cut it back by an inch if it's not that i just used number plate double sided sticky pads and stuck it to the peace where the towing eye hole is.
Sorry, I meant the plate being recessed. I have mesh behind the bumper so not sure what you stuck it to?
on the bunper right in the middle there is a square piece with a hole in it for the towing eye ive stuck the number plate to that piece see pic below
